SPRINKLER HEAD.

Application filed November 26, 1924. Serial No. 752,408.

To all whom it may concern.-

Be it known that .I, Josnrrr Knnrzrenn, a citizen of the United States, and a resident of Los Angeles, in the county of Los Angeles and State of California, have invented certain new and useful Improvements in Sprinkler Heads, of which the following is a specification.

My invention relates to lawn sprlnkler heads of the type which is adjustable for the purpose of varying the area of lawn sprinkled and it is a purpose of my invention to provide a sprinkler head which is adjustable to control the pressure of the water discharged therefrom whereby the trajectory of the spray and, consequently, the area of the lawn sprinkled can be varied at will.

I will describe only one form of sprinkler head embodying my invention and will then point out the novel features thereof in claims.

In the drawings,

Figure 1 is a view showing in top plan one form of sprinkler head embodying my invention;

Figure 2 is a vertical sectional view of the sprinkler head shown in Figure 1 in applied position to one of the pipes of a sprinkler system.

Referring specifically to the drawings, in which similar reference characters refer to similar parts in each of the views, my invention, in its present embodiment, is shown as comprising a body formed of metal or other suitable material and including a tubular portion 15 closed at its upper end by a head or top portion 16 preferably formed integral with the tubular portion. The portion 15 is provided with a threaded bore 17 which receives the threaded end of a pipe 18 constituting one of the pipes of the sprinkler system through which water under pressure is supplied to the head. Above the bore 17 is a smooth bore 19 of the same diameter as threaded bore 17, while above the former is a bore 20 of a reduced diameter so as to provide at the junction of the bores 19 and 20 an annular shoulder 21. This shoulder 21 is widened by the formation of a groove 22 in the bore 19, such groove being of a contour to receive a plate ordisk 23.

As illustrated in dash lines in Figure 2, the plate 28 is normally of concavo-convex form when inserted into the tubular portion and of such diameter as to engage the shoulder 21 so that by inserting a suitable instrument into the tubular portion and hammering the same the plate will be flattened to the position illustrated in solid lines wherein its beveled periphery is forced into the groove 22, thus locking the plate in spanning position within the tubular portion.

This plate 23 co-operates with the head or top portion 16 to provide a chamber 24 to which water from the pipe 18 is admitted through a port 25 controlled by a valve 26 formed in the lower end of a screw 27 threadedly fitted in the head 16 so as to move vertically when rotated and thus open or close the port 25.

Water from the chamber 24 is discharged from the sprinkler head through a port 28 formed in the head 18 and including a lateral passage 29 designed to set up a fanshaped spray of the water emanating there-- from. The head 17 is recessed to facilitate manipulation of the screw 27 and free passage of the water from the passage 29.

In practice, the volume of water supplied to the chamber 24 can be readily controlled by an adjustment of the valve 26, and it will be understood that because of the relatively large capacity of the chamber 24 with respect to the discharge port 28 that any variance of the volume of water supplied tothe chamber will operate to vary the pressure of water discharged from passage 29 and, as a consequence, the trajectory of the spray will be changed accordingly. That is to say, by increasing or decreasing the volume of water supplied to the chamber 24 the pressure of water discharged through the passage 29 is increased or decreased accordingly, so that the trajectory of the spray is likewise increased or decreased.

From the foregoing operation, it will be manifest that through an adjustment of the valve 26 the trajectory of the spray can be varied at will so as to sprinkle a predetermined area of lawn.

Although I have herein shown and described only one form of sprinkler head embodying my invention, it is to be understood that various changes and modifications may be made without departing from the spirit of the invention and the spirit and scope of the appended claims.

I claim as my invention:

1. A sprinkler head comprising a body formed to provide a chamber, one wall of the chamber having an inlet port through which water under pressure from a source of supply enters the chamber, a discharge port communicating with the chamber and formed to project a fan shaped spraytoone side of the head, and valved means adjustable in the body to control the passage of water through the inlet port in Such manner that the water will be caused to strike the roof of thechamber and completely fill the latter before entering thefldischarge ,port, whereby thelatter will becompletely filled and project an vevenly distributed spray.
